Abstract

The existence of a Regional Drinking Water Company (PDAM) is very important in maintaining the continuity of the clean water treatment process running smoothly and well. Maintenance of clean water distribution machines and equipment is a matter that requires attention because damage to one of the machines or equipment can cause a cessation of processing activities which results in losses for companies and services. Damage to the water distribution machine in PDAM Tirta Mountala is unavoidable and this happens frequently. This happens because the damage is not properly identified, either in preventive maintenance or in anticipating appropriate action. The purpose of this study is to identify the cause of the damage and propose maintenance actions on the clean water distribution pump machine in PDAM Tirta Montala Aceh Besar. The failure mode and effect analysis (FMEA) and logic tree analysis (LTA) approaches are used to anticipate this. FMEA is an approach used to identify and analyze potential failures and their consequences. Meanwhile, LTA aims to prioritize each damage mode and carry out reviews and functions, malfunctions so that the damage mode status is not the same. There are eighteen water distribution pump components with the highest damage frequency. Based on the results of the FMEA, five components with the highest RPN or the highest risk were obtained, namely the vane, stuffing box, bearing bracket support, shaft and bearing components. The five components were then analyzed through LTA and maintenance tasks with several proposed actions including repair, component replacement, welding, thermography, and re-measurement with a vibration meter.

Abstract

This research aims to analyze the financial feasibility and sensitivity of investment in the rejuvenation of smallholder oil palm plantations in Lungmane Village, Kuala Pesisir Subdistrict, Nagan Raya Regency, Aceh Province, amidst the problem of declining Fresh Fruit Bunch (FFB) productivity due to aging trees. The research method used is quantitative analysis with investment criteria of Net Present Value (NPV), Internal Rate of Return (IRR), Net Benefit-Cost Ratio (Net B/C), and Payback Period (PP), as well as sensitivity analysis to changes in FFB prices. The results of the analysis show that the rejuvenation project for smallholder oil palm plantations in Lungmane Village is financially feasible based on positive NPV, IRR, Net B/C, and Payback Period indicators. However, the sensitivity analysis reveals that the project's feasibility is highly influenced by fluctuations in FFB prices, where a price decrease of up to 70% can render the project unfeasible. This study concludes that although the rejuvenation of smallholder oil palm plantations in Lungmane Village has good financial prospects, farmers need to be aware of the risk of declining FFB prices.
